NZ Transport Agency Waka Kotahi (NZTA) is advising drivers to plan ahead for multiple night-time closures on State Highway 1 (SH1) between Fanshawe Street and Greenlane (southbound) over the next two weeks. The road closures are required for NZTA contractors to carry out essential work, including paving and stormwater maintenance.

State Highway 16 (SH16) between Stanley Street and Wellesley Street (westbound) will also be closed.

The southbound closures are scheduled between 10pm and 5am on:

• Sunday 20 July
• Tuesday 22 July
• Thursday 24 July
• Monday 28 to Wednesday 30 July

For people travelling south on SH1, there will be a signposted detour via SH16 link to Port, Wellesley St, Grafton Rd, Khyber Pass Rd, Broadway, Great South Rd and Greenlane East. Emergency services will need to use the detour routes.

These works are weather dependent and contingency dates have been put aside for 31 July, 7 and 8 August. Please check the Journey Planner for real-time information.

From Monday 28 July, the closure may be shortened from Gillies Ave to Greenlane. If you would like to stay updated, please sign up to email alerts here.

Ramp closures and lane restrictions may be in place before the advertised closure times for the mainline.
